Not able to drag and drop transitions to To-do and In-progress status and not able to drag and drop/create transitions to Done status.

Steps to Reproduce

1. Access Jira Service Desk project settings > Request types > Edit Workflow;
2. Create/add a Done status on your workflow;
3. Try to drag and drop/add a transition to the status created/added above;
4. Provide the transition name and hit Create.

Expected Results

The transition is created successfully.

Actual Results

At console the following error is being thrown:

react-dom.production.min.js:187 TypeError: Cannot read property 'length' of undefined

Workaround

Instead of drag and drop, add the transition by clicking on the top menu Transition. It only works for To-do and In-progress status.

Notes

The above workaround does not work for Done statuses.
